Incident Light And Morphology Determine Coral Productivity Along A Shallow To Mesophotic Depth Gradient, Michael P. Lesser, Marc Slattery, Curtis D. Mobley

Faculty and Student Publications

While the effects of irradiance on coral productivity are well known, corals along a shallow to mesophotic depth gradient (10–100 m) experience incident irradiances determined by the optical properties of the water column, coral morphology, and reef topography. Modeling of productivity (i.e., carbon fixation) using empirical data shows that hemispherical colonies photosynthetically fix significantly greater amounts of carbon across all depths, and throughout the day, compared with plating and branching morphologies. In addition, topography (i.e., substrate angle) further influences the rate of productivity of corals but does not change the hierarchy of coral morphologies relative to productivity. The differences in …

Sequentialdynamics Of Stearoyl-Coa Desaturase-1(Scd1)/Ligand Binding And Unbinding Mechanism: A Computational Study, Anna B. Petroff, Rebecca L. Weir, Charles R. Yates, Joseph D. Ng

Faculty and Student Publications

Stearoyl-CoA desaturase-1 (SCD1 or delta-9 desaturase, D9D) is a key metabolic protein that modulates cellular inflammation and stress, but overactivity of SCD1 is associated with diseases, including cancer and metabolic syndrome. This transmembrane endoplasmic reticulum protein converts saturated fatty acids into monounsaturated fatty acids, primarily stearoyl-CoA into oleoyl- CoA, which are critical products for energy metabolism and membrane composition. The present computational molecular dynamics study characterizes the molecular dynamics of SCD1 with substrate, product, and as an apoprotein. The modeling of SCD1:fatty acid interactions suggests that: (1) SCD1:CoA moiety interactions open the substrate-binding tunnel, (2) SCD1 stabilizes a substrate conformation …

Structural And Kinetic Analyses Of Holothurian Sulfated Glycans Suggest Potential Treatment For Sars-Cov-2 Infection, Rohini Dwivedi, Priyanka Samanta, Poonam Sharma, Fuming Zhang

Faculty and Student Publications

Certain sulfated glycans, including those from marine sources, can show potential effects against SARS-CoV-2. Here, a new fucosylated chondroitin sulfate (FucCS) from the sea cucumber Pentacta pygmaea (PpFucCS) (MW ∼10.60 kDa) was isolated and structurally characterized by NMR. PpFucCS is composed of {→3)-β-GalNAcX-(1→4)-β-GlcA-[(3→1)Y]- (1→}, where X = 4S (80%), 6S (10%) or nonsulfated (10%), Y = α- Fuc2,4S (40%), α-Fuc2,4S-(1→4)-α-Fuc (30%), or α-Fuc4S (30%), and S = SO3-. The anti-SARS-CoV-2 activity of PpFucCS and those of the FucCS and sulfated fucan isolated from Isostichopus badionotus (IbFucCS and IbSF) were compared with that of heparin. IC50 values demonstrated the activity of …

Are Rural And Small Community Aerated Wastewater Stabilization Ponds A Neglected Source Of Microplastic Pollution?, Zhiqiang Gao, James V. Cizdziel, Kendall Wontor, Haitao Lu

Faculty and Student Publications

Wastewater treatment systems collect and treat sewage that includes microplastics (MPs). However, we are not aware of any studies on the occurrence and distribution of MPs in wastewater stabilization ponds (WSPs), which serve small communities worldwide. Here, we characterized MPs (~45 µm–5 mm) in an aerated WSP serving ~500 houses and an adjacent lake. Putative MPs were most abundant in duckweed (Lemna minor) and sludge (75 ± 22 and 12.8 ± 3.1 particles/g, respectively: ±1 standard deviation (SD), n = 6, dry weight). In the water, average concentrations (particles/L ± 1 SD, n = 6) were highest in the pond …

Weak Spatial-Genetic Structure In A Native Invasive, The Southern Pine Beetle (Dendroctonus Frontalis), Across The Eastern United States, Ryan C. Garrick, Ísis C. Arantes, Megan B. Stubbs, Nathan P. Havill

Faculty and Student Publications

The southern pine beetle, Dendroctonus frontalis, is a native pest of pine trees that has recently expanded its range into the northeastern United States. Understanding its colonization, dispersal, and connectivity will be critical for mitigating negative economic and ecological impacts in the newly invaded areas. Characterization of spatial-genetic structure can contribute to this; however, previous studies have reached different conclusions about regional population genetic structure, with one study reporting a weak east-west pattern, and the most recent reporting an absence of structure. Here we systematically assessed several explanations for the absence of spatial-genetic structure. To do this, we developed nine …

Growth And Feeding In The Sponge Agelas Tubulata From Shallow To Mesophotic Depths On Grand Cayman Island, Keir J. Macartney, Amelia Clayshulte Abraham, Marc Slattery, Michael P. Lesser

Faculty and Student Publications

On Caribbean coral reefs, sponges are important members of the benthic community and play multiple roles in ecosystem structure and function. They have an important role in benthic-pelagic coupling, consuming particulate organic matter (POM) and dissolved organic matter (DOM) and in turn providing food in the form of sponge biomass or the release of detritus for a variety of coral reef organisms. Throughout the Caribbean, sponges show consistent increases in their abundance and growth rates as depth increases into the mesophotic zone (30–150 m). This has been hypothesized to be driven by bottom-up forces, particularly the increased supply of nitrogen-rich …

Targeted Downregulation Of Myc Through G-Quadruplex Stabilization By Dnai, Alexandra Maria Psaras, Katarina T. Chang, Taisen Hao, Tracy A. Brooks

Faculty and Student Publications

Modulating the expression or function of the enigmatic MYC protein has demonstrated efficacy in an array of cancer types and a marked potential therapeutic index and safety profile. Despite its high therapeutic value, specific and selective inhibitors or downregulating therapeutics have proven difficult to develop. In the current study, we expanded our work on a MYC promoter G-quadruplex (G4) stabilizing DNA clamp to develop an oligonucleotide interfering DNA (DNAi) therapeutic. We explored six DNAi for G4-stabilization through EMSA, DMS footprinting, and thermal stability studies, focusing on the DNAi 5T as the lead therapeutic. 5T, but not its scramble control 5Tscr, …
